"2 large upright catalogue files (48 x 18 x 24 in.), and two small filing cabinets (12 x 6 x 24 in.), each containing thousands of jokes typewritten on 3 x 5 in. cards and indexed by subject. Together with 6 banker's boxes of loose joke file material, including cue cards and other related items.

Meticulously maintained by Berle over the course of his long career, the 'joke file' was considered by him to be the most valuable resource in his office."
